STRIP-WINDING nnvrcn.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed August 1, 1918. Serial No. 247,764.

To all whom it may concern:

Be it known that I, ALBERT H. De Von, a citizen of the United States, residing at lVestfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in StripWinding Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to strip winding devices for rolling up bias cut strips of mate rial in a smooth compact condition convenient for subsequent use on a sewing machine in binding or other operations.

Bias cut strips curl and rope up when free to assume whatever condition they will and for this reason it is desirable to iron them flatand to wind them under a moderate amount of tension into a compact roll. The present invention provides a simple and inexpensive construction for doing so with little or no more skill on the part of the operator than is required to handle non-bias cut strips or tape. It also aims to expedite re moval of the roll when completely wound and to capacitate the device for strips of different widths, from the widest to the narrowest that are likely to be used in subsequent stitching operations. y

In its embodied form the invention comprises a one-sided reel on opposite sides of Whose axis are disposed a pair of pins. The

reel is rotatably supported in a standard sustaining horizontally a'rod at the free end of which is pivoted an arm movable in a plane transverse the axis of the reel. On the arm is conveniently secured a base-plate having a smooth upper surface for cooperation with an ironing plate of nearly triangular form which is articulated to a link for movement relative to the base-plate about angularly disposed axes parallel therewith, while the link is hinged to the arm supporting the base-plate to permit separation of the ironing and base-plates for convenient introduction between them of a bias out strip. The base and ironing plates are adapted to move outward in a nearly radial direction as the material accumulates, constantly maintaining a light pressure on the material already wound as well as uncurling and applying tension to the strip in its passage to the reel. An edge-guide is provided on the base plate adjacent the spider forming the side of the reel and the rod, to which the arm carrying the baseplate is pivoted, is adjustable in the standard for convenience in locating the ends of the "base and ironing plates relative to the axis of the reel.

The invention is illustrated in the accompanying. drawings in which, Figures 1 and 2 are side and plan views respectively of the attachment. 1

The reel is supported by a standard 1 having a foot 2 notched as indicated at 3 to receive suitable fastening screws. At the upper end of the standard 1 a bearing 4 is pr0- vided for a shaft 5 embraced at one end by the split collar 6 of a crank 7 and carrying at its other end a spider 8 which constitutes one side of the reel. Pins 9 project laterally from the spider 8 in parallelism a short distance on either side of the axis of the shaft 5 prolonged. I Beneath the bearing l is transversely disposed a boss 10 apertured horizontally to re ceive a rod 11 adjustably secured therein at one end by the screw 12. The other end of the rod 11 is bent as indicated at 11' into parallelism with the axis of the reel and adjustably secured thereon are the spaced collars 13 between which is confined the elongated sleeve lt of an arm 15 carrying at its free end a base-plate 16 having a smooth upper surface.

Beneath the baseplate 16 the arm is drilled in a direction parallel to the axis of the reel to receive the bent end 17 of a U- shaped link 18 whose other bent end 19 is also arranged in parallelism with the axis of the reeland is reducedto form the restraining shoulders 20 between which are loosely confined the ears 9.1 of a lug 22 integral with an ironing plate 23 which is substantially triangular and has its sides 23 inclined upwardly toward each other. A pin 9A passed through the ears 21 holds the ironing plate loosely in place. Preferably the shoulders 20 are farther apart than the width of the ears 21to permit movement of the ironing plate 23 about angularly disposed axes which are parallel tothe base-plate 16. By hinging the end 17 of the link 18 to the arm .15 in the manner disclosed, separation of the ironing plate 23 from the base-plate 16 is permitted for convenient introduction of the strip between them and for the accommodation of different thicknesses of material. An edge-guide 25 integral with the of the reel.

' 1 uncurlin base-plate 16 is also provided for guiding one edge of the tape while it is being wound. In the use of the attachment the operator lifts on the link 18 to separate the ironing 5 plate 23 ,from the base-plate 16 and introduces the strip therebetween with a short length projecting. This short projecting end is inserted between the pins 9 and the crank 7 rotated to wind the strip into a roll. 10 As the strip accumulates the base-plate which restsupon the already wound strip and the ironing plate which rests upon the strip passing to the reel both move in a nearly radialdirection away from the aX1s Thus in a neat and eflicient manner the operator is enabled towind bias out strips into a roll simultaneously uncurl- -ing"andltensioning the strip as it passes to the reel. After the roll is wound the strip inay becut off from the supply; Then the loperator may grasp: the roll and pull it off of the pins 9 havingpreviously swung the arm up out of the way if desired.

, Itwill be noticed that the attachment is capable of handling various widths of bias out strips and that the'edge-guide carried by the base plate will space one edge of the strip as it is being wound a suflicient d1s- *tance from the spokes of the spider 8 to prevent the raw edges curling aboutthe sides of the spokes in a manner likely to'resist re- -moval of the wound rOll'from OK the pins 9. Having thus set forth the nature of the invention, what I claim herein isv 1 1.
